This is such a strange an infuriating issue.

I'm trying to develop with the Instagram API via Instagram Basic Display to publish content to my business' Instagram feed. Part of this means I am trying to generate an Access Token for that account.

I go through the process of giving permission for the Instagram account to access the App, and at the end I am given a pop up asking me to understand the responsibility of this token, and I am then given a long life access token. I click close on the pop up. On the Basic Display page on my App Dashboard, next to my Instagram account, it states "Token Generated".

Regardless of if I click "Save Changes" on that page, regardless of what browser I am using etc, no matter what I do the generated Access Token does not persist on this page. I've gone through the same process a number of times and I still get the same result.
